【摘要】：相較于傳統(tǒng)變電站,智能變電站的整個(gè)過(guò)程層已實(shí)現(xiàn)網(wǎng)絡(luò)化。無(wú)論是一次系統(tǒng)的實(shí)際運(yùn)行數(shù)據(jù),還是二次設(shè)備之間的相互通信,都以報(bào)文的形式進(jìn)行傳輸,但是報(bào)文不同于傳統(tǒng)的測(cè)量值,比較復(fù)雜,要求運(yùn)行維護(hù)人員對(duì)IEC61850規(guī)約相當(dāng)熟悉才能分析,這給數(shù)字化變電站的運(yùn)行、維護(hù)及事故原因判斷、檢修等日常工作帶來(lái)了極大的不便。本論文目的就是研究智能變電站對(duì)網(wǎng)絡(luò)報(bào)文分析系統(tǒng)的功能需求,設(shè)計(jì)一種可以對(duì)過(guò)程層主要報(bào)文類(lèi)型(SV、GOOSE)進(jìn)行捕捉、記錄并完成分析的軟件。主要研究?jī)?nèi)容及成果如下:首先,對(duì)傳統(tǒng)變電站的局限性做出了分析,并介紹了IEC61850標(biāo)準(zhǔn)、特點(diǎn)以及關(guān)鍵技術(shù),對(duì)比了智能變電站與傳統(tǒng)型變電站的優(yōu)缺點(diǎn)。針對(duì)過(guò)程層主要的兩種報(bào)文類(lèi)型(SV、GOOSE)都從結(jié)構(gòu)、幀格式以及通信模式等方面做了詳細(xì)的分析。接著,對(duì)軟件設(shè)計(jì)做了總體性的概述,并將其按照不同的功能分為捕獲,存儲(chǔ),解析,歷史數(shù)據(jù)檢索,分析處理等多個(gè)模塊。接著針對(duì)各個(gè)模塊進(jìn)行了流程設(shè)計(jì),并提出了實(shí)現(xiàn)方法。然后針對(duì)目前大容量?jī)?chǔ)存方式存在的一些弊端,采用了一種較為新穎的多硬盤(pán)多分區(qū)的循環(huán)儲(chǔ)存方式,有效避免了頻繁讀寫(xiě)導(dǎo)致的硬盤(pán)受損。最后通過(guò)搭建測(cè)試環(huán)境,對(duì)所設(shè)計(jì)功能模塊進(jìn)行了模擬測(cè)試,測(cè)試結(jié)果得出本文所設(shè)計(jì)的網(wǎng)絡(luò)報(bào)文記錄分析軟件可以較好的完成相應(yīng)的功能。
[Abstract]:Compared with traditional substation, the whole process layer of intelligent substation has been networked. Both the actual operation data of the primary system and the communication between the secondary devices are transmitted in the form of message, but the message is different from the traditional measurement value and is more complex. The operation and maintenance personnel are required to be familiar with IEC61850 protocol before analyzing, which brings great inconvenience to the operation, maintenance, accident reason judgment, repair and other daily work of digital substation. The purpose of this paper is to study the functional requirements of the network message analysis system in intelligent substation, and to design a software which can capture, record and complete the analysis of the main message types in the process layer. The main research contents and results are as follows: firstly, the limitations of traditional substation are analyzed, and the IEC61850 standard, characteristics and key technologies are introduced, and the advantages and disadvantages of intelligent substation and traditional substation are compared. The two main message types in the process layer are analyzed in detail, such as structure, frame format and communication mode. Then, the software design is summarized, and it is divided into capture, storage, analysis, historical data retrieval, analysis and processing modules according to different functions. Then, the process of each module is designed, and the implementation method is put forward. Then, aiming at some disadvantages of the current mass storage mode, a novel multi-disk and multi-partition cyclic storage mode is adopted, which can effectively avoid the damage of hard disk caused by frequent reading and writing. Finally, by setting up a test environment, the designed functional modules are simulated and tested. The test results show that the network message recording and analysis software designed in this paper can accomplish the corresponding functions better.
